Hi there,
As I can't leave my house, I try to fix issues on my DIY modules.
MY CGS 116 is weird.
The module works because I can do all shapes possibles but some pots are reverted and also CV inputs.
I checked several times the wiring and it's like indicated on Ken stone's instructions.
I report here how differents controls act:

I’ve just built the new Elby version which works
The pots should be voltage dividers between +12v and GND
Sounds like you may have connected to -12v by mistake
I did not build mine with the matched transistors
Can someone tell me if that might cause any issues - possibly inconsistent timing due to temperature variations?

Ok, great! I'll reverse connections.
And for the non-working Decay Pot? The CV input works, I checked and the pot center leg is well connected to the same point than the CV input via 2 differents resistors (82k & 110k).
Thanks

yes, you're right, I'll use it in this way.
about something else the bad producer, I don't understand how do you wire your serge phaser panel
The upper part is just a 2 input mixer? and at the bottom feedback pot is to send it back to phaser's input?
But you may don't want to share your building techniques... sorry if I ask to much

Ah yes indeed I should post the wiring, but basically on the phaser PCB there are two mixers, one is the mixer at top of panel, the other I use to mix inputs. Input to phaser goes to mixer first, output of mixer goes to input of phaser, feedback pot is amount of phaser output going in the the mixer, does that make sense? I’ll try and get diagram up soon!
